Son of my sister, by Allah, I used to see the new moon, then the new moon, then the new moon, i. e. three moons in two months, and fire was not kindled in the house of Messenger of Allah ﷺ. I ('Urwa) said: Auntie, then what were your means of sustenance? She said: Dates and water. But it (so happened) that Messenger of Allah ﷺ had some Ansar as his neighbours and they had milch animals and they used to send to Messenger of Allah ﷺ some milk of their (animals) and he served that to us. (Using translation from Muslim 2972c)
أَنَّهَا كَانَتْ تَقُولُ وَاللهِ يَا ابْنَ أُخْتِي إِنْ كُنَّا لَنَنْظُرُ إِلَى الْهِلَالِ ثُمَّ الْهِلَالِ ثُمَّ الْهِلَالِ ثَلَاثَةَ أَهِلَّةٍ فِي شَهْرَيْنِ وَمَا أُوقِدَتْ فِي أَبْيَاتِ رَسُولِ اللهِ ﷺ نَارٌ قَالَ قُلْتُ يَا خَالَةُ مَا كَانَ يُعِيشُكُمْ؟ قَالَتِ الْأَسْوَدَانِ التَّمْرُ وَالْمَاءُ إِلَّا أَنَّهُ قَدْ كَانَ لِرَسُولِ اللهِ ﷺ جِيرَانٌ مِنَ الْأَنْصَارِ وَكَانَتْ لَهُمْ مَنَائِحُ فَكَانُوا يُرْسِلُونَ إِلَى رَسُولِ اللهِ ﷺ مِنْ أَلْبَانِهَا فَيَسْقِينَاهُ
